Since I rebuilt the top end a month or so back, power's been up but there are some disturbing noises coming from the engine. At start up there is a nasty knocking: http://homepage.ntlworld.com/mark.seaton2/Nasty%20knock%203.wav I'm at a loss as to what it is. I thought perhaps an exhaust leak, but all the nuts are tight. I double checked the lower head nuts and they were good. It seems to come from the left bank and almost goes away after she warms up. When she's warm thought there is another more disturbing sound: http://homepage.ntlworld.com/mark.seaton2/Nasty%20Rasping%20Noise%203.wav I thought at first that this must be the fan rubbing on the housing- I did have that all apart when the engine was out. The end-float was a little tight and there was no gasket under the flywheel so I put a thin paper one under there. I was thinking that this might be the result of too much end-float allowing the fan to rub. Last night I was thinking about it some more and there are a few other things I want to check- the tin screws which I replaced for stainless allen screws for ease of removal next time were a bit long and might be rattling against something?. Any other ideas? All suggestions appreciated cos it sounds like I'm destroying her even though she's running better than ever!
